Level 9 was a British computer text adventure game company which produced some of the most advanced games of the 1980s. Founded in 1981 by Michael, Nicholas and Pete Austin, the company produced about 20 games for BBC Micro, Nascom, ZX Spectrum, Commodore 64, Oric, Atari, Lynx 48k, RML 380Z, Amstrad CPC, MSX, Amiga, Apple II, Memotech MTX, and Enterprise until the commercial declining market of the text adventure genre forced their closure in June 1991.

Level 9's first program was an extension to Nascom BASIC called Extension Basic. The first game, also for the Nascom, was called Fantasy and was similar to Valhalla, but with no graphics. Other products from that era were Missile Defence, Bomber and Space Invasion -- all for the Nascom. The tapes were duplicated and sent out by mail order by the brothers based on orders generated by the classified advertisements they ran in the Computing Today magazine. They were based at Hughenden Road, High Wycombe, Bucks. HP13 5PG before moving to the West Country.
